Improving proprioception can reduce the risk of injuries, while its disruption may lead to injuries and recurrent or persistent symptoms.
This study aimed to evaluate the immediate effects of elbow orthoses on elbow proprioception in asymptomatic individuals.
This was a randomized, controlled, single-blinded study with a sham application.
Sixty participants were equally distributed into three orthosis groups (counterforce, sleeve, and sham). Proprioception was assessed using active joint position sense error (JPSE) at 70° and 110° of elbow flexion at three time points: baseline (BS), immediately after (IA) wearing the orthosis, and 30 minutes after (30MA) wearing the orthosis.
Between groups: No significant difference in JPSE was observed at 70° (p = 0.095); however, there was a significant difference at 110° (p = 0.005). Between time points: At 70°, JPSE did not exhibit a significant difference (p = 0.055), whereas a significant difference was observed at 110° (p = 0.020). Interaction of time points×groups: No significant interaction was observed either at 70° (p = 0.476) or at 110° (p = 0.346). At 70°, within the sleeve group, significant differences were identified between BS-30MA (p = 0.001) and IA-30MA (p = 0.009). At 110°, in the sleeve group, significant differences were observed between BS-30MA (p = 0.007) and IA-30MA (p = 0.007). In the counterforce group, significant differences were identified between BS-30MA time points (p = 0.001). At 70°, no difference was observed within the overall evaluation in the counterforce group (p > 0.05), whereas at 110°, a significant difference was noted (p = 0.026). At both 70° and 110°, no differences were identified within the overall evaluation in the sleeve and sham groups (p > 0.05).
In asymptomatic individuals, sleeve orthosis improved elbow proprioception at 70°, whereas both counterforce and sleeve orthoses were effective at 110°.
改善本体感觉可以降低受伤的风险，而本体感觉的丧失可能导致受伤和反复或持续的症状。
本研究旨在评估肘矫形器对无症状个体肘本体感觉的即时影响。
这是一项随机、对照、单盲研究，采用假应用。
60 名参与者被平均分配到三个矫形器组（反作用力、套管和假）。使用主动关节位置感误差（JPSE）在三个时间点评估本体感觉：基线（BS）、佩戴矫形器后立即（IA）和佩戴矫形器 30 分钟后（30MA）。
组间：70°时 JPSE 无显著差异（p=0.095）；然而，在 110°时存在显著差异（p=0.005）。时间点间：在 70°时，JPSE 无显著差异（p=0.055），而在 110°时存在显著差异（p=0.020）。时间点×组间的交互作用：在 70°时无显著交互作用（p=0.476），在 110°时也无显著交互作用（p=0.346）。在 70°时，套管组中 BS-30MA（p=0.001）和 IA-30MA（p=0.009）之间存在显著差异。在 110°时，套管组中 BS-30MA（p=0.007）和 IA-30MA（p=0.007）之间存在显著差异。在反作用力组中，BS-30MA 时间点之间存在显著差异（p=0.001）。在整体评估中，在 70°时，反作用力组无差异（p>0.05），而在 110°时存在显著差异（p=0.026）。在 70°和 110°时，套管和假组的整体评估中均无差异（p>0.05）。
在无症状个体中，套管矫形器可改善 70°时的肘本体感觉，而反作用力和套管矫形器在 110°时均有效。
